Hi Guys,

When I run cases from QC I get this status very often "Unable to open test in test tool". I see QTP open but the test case is not executed.
The Test Lab window just shows the previous result and doesn't show any details of the current run. It is the same case if the host is local or any other machine.
Around 30% of the times I see this. Any idea what going wrong?
Any input would be great.
